Designing Roller Coasters

Front

Electromagnetism Noun

---

[uh-lek-troh-mag-ni-tiz-uhm]

Back

Electromagnetism

---

A fundamental force of nature that can be attractive or repulsive, involving electric and magnetic fields.

---

Example: This diagram shows how electricity creates a magnet. When electric current from the battery flows through the coiled wire, the iron bar inside becomes a temporary magnet with a north and south pole.

Front

Attract Verb

---

[uh-trakt]

Back

Attract

---

To pull another object closer through a force like magnetism or gravity.

---

Example: This diagram shows two bar magnets where the opposite poles (North and South) are facing each other, causing them to pull together or attract.

Front

Repel Verb

---

[ri-pel]

Back

Repel

---

To push another object away through a force like magnetism.

---

Example: When two similar magnetic poles, like two North poles, are brought near each other, they push each other away with a force.

Front

Magnetic Field Noun

---

[mag-net-ik feeld]

Back

Magnetic Field

---

A region around a magnetic object or electric current where a magnetic force is exerted.

---

Example: This image shows the invisible magnetic field around a bar magnet, with arrows pointing from the North pole to the South pole.

Front

Magnetic Field Lines Noun

---

[mag-net-ik feeld layns]

Back

Magnetic Field Lines

---

Imaginary lines used to represent the direction and strength of a magnetic field.

---

Example: This diagram shows the invisible magnetic field lines around a bar magnet, with arrows indicating they travel from the North pole to the South pole.

Front

Magnetic Pole Noun

---

[mag-net-ik pohl]

Back

Magnetic Pole

---

The regions at each end of a magnet where the external magnetic field is strongest.

---

Example: This diagram shows a magnet's two poles, North (N) and South (S), which are the areas where the magnetic force is strongest.

Front

Electromagnet Noun

---

[uh-lek-troh-mag-nit]

Back

Electromagnet

---

A temporary magnet created by passing an electric current through a coil of wire, often wrapped around an iron core.

---

Example: This diagram shows that when electric current flows through a coil of wire wrapped around a core, it creates a temporary magnetic field.

Front

System Noun

---

[sis-tuhm]

Back

System

---

A group of interacting objects or parts that are being studied as a whole.

---

Example: The Earth and Moon form a system where the parts (Earth, Moon) interact through gravity, causing the Moon to orbit the Earth.

Front

Potential Energy Noun

---

[puh-ten-shuhl en-er-jee]

Back

Potential Energy

---

Stored energy an object has because of its position or state.

---

Example: A large ball pushed high up a hill has a lot of stored (potential) energy because of its height above the ground.

Front

Kinetic Energy Noun

---

[ki-net-ik en-er-jee]

Back

Kinetic Energy

---

The energy an object possesses due to its motion.

---

Example: A soccer ball flying through the air has kinetic energy because it is an object in motion.
